Flutter SfCircularChart 周围的额外间距

发布于12月30日

这是我第一次在这里提问.我想知道如何从syncfusion_flutter_charts包中go 掉SfCircularChart周围多余的空格.

Container(
 // Wrapping around fixed size Container
 width: 200,
 height: 200,
 color: Colors.red,
 child: SfCircularChart(
  // Setting the margin to zero
  margin: EdgeInsets.zero,
  series: <CircularSeries>[
   PieSeries<Category, String>(
    dataSource: dailyEarningList,
    xValueMapper: (Category data, _) => data.name,
    yValueMapper: (Category data, _) => data.value,
    dataLabelSettings: DataLabelSettings(
     isVisible: true,
    ),
   ),
  ],
 ),
)

推荐答案

PieSeries<Category, String>(
            radius: "100",
            dataSource: [Category(["a", "b", "c"])],
            xValueMapper: (Category data, _) => "d",
            yValueMapper: (Category data, _) => 1,
            dataLabelSettings: const DataLabelSettings(
              isVisible: true,
            ),
          ),

该库具有半径参数.这是一根线.我不明白为什么它是一根线.在您的示例中，如果将其设置为"100"，它将与容器匹配.
